Procedure

Following the general procedure for carbodiimide formation outlined in example 12, N-(2-methylphenyl)-N′-[4-chloro-2-tert-butyldimethylsilyloxy-3-(N″,N″-dimethylaminosulfonyl)phenyl]thiourea (410 mg, 0.8 mmol), methanesulfonyl chloride (0.14 mL, 1.6 mmol) and triethylamine (0.23 mL, 1.6 mmol) were reacted to form the desired product (400 mg, crude). 1H NMR (CDCl3) δ 0.39 (s, 6H), 1.05 (s, 9H), 1.72 (m, 4H), 2.37 (s, 3H), 2.87 (s, 6H), 7.04 (d, 1H), 7.18 (m, 4H), 7.29 (d, 1H).
